Question
The fossil bone has a 14C : 12C ratio, which is 
f that in a living animal bone. If the half life time of 14C is 5730 years, then age of the fossil bone is
f that in a living animal bone. If the half life time of 14C is 5730 years, then age of the fossil bone isOptions
A.11460years
B.17190years
C.22920years
D.45840years
Solution
Let 
be the intial ratio of 14C : 12C. Let it is 
in the fossil. As q remains constant, p must have reduced to
during the period.
No. of half lives required = 4
Age of fossil = 4 × 5730 = 22920
